Also, if you are receiving a blue screen error look it up. When I had this happen to me a couple of times it was due to the hard drive being set to SATA instead of ACHI or combination. Just something to think about.

When I tried cracking WEP I didn't find commview for wifi a good enough tool. I recommend using airodump and aircrack if your card is supported. If not, you can do what I did and buy a new wireless card. The linux tools just work a lot better.
